AUTOMATIC TIGHT 0 R HEAT REGULATOR.

Application filed February 19, 1915.

To all whom it may concern Be it known that I, YosrIIsUKI HANAOKA, a subject of the Emperor of Japan, residing at l-lilo, in the Territory of Hawaii, have invented certain new and useful Improve ments in Automatic Light or Heat Regulators, of which the following is a specification.

This invention relates to a self-contained automatic device forturning on or 0H light or heat at predetermined times.

One of the objects of the present inven tion is to provide a reliable and eflicient device of the above general character which will be simple and practical in construction.

A further object is to provide a device of the above mentioned character having few parts which will be cheap to manufacture and install.

Other objects will be in part obvious from the annexed drawings and in part indicated in connection therewith by the following analysis of this invention.

This invention accordingly consists in the features of construction, combination of parts and in the unique relations of the members and in the relative proportioning and disposition thereof; all as more completely outlined herein.

To enable others skilled in the art so fully to comprehend the underlying features thereof that they may embody the same by the numerous modifications in structure and relation contemplated by this invention, drawings depicting a preferred form have been annexed as a part of this disclosure, and in such drawings, like characters of reference denote corresponding parts throughout all the views, of which 1- Figure 1 is a semi-diagrammatic elevational view of the complete device in set position; Fig. 2 is a similar view with the parts in operative position; Fig. 3 is an end sectional elevational view taken on the line 33 of Fig. 1; Fig. 4: is a plan view of the part shown in Fig. 2; and Fig. 5 is a detail view. Fig. 6 is another detail view.

The present invention will hereinafter be described with relation to its application to the automatic regulation of light, that is, a light which is automatically turned on and ofl at predetermined times, such for example, as a night light in a street or building, although it is, of course, to be understood that without material modification, it may be applied to the automatic operation Specification of Letters Patent.

Referring now to the drawings in detail and more particularly to Fig. 1, 10 denotes a clock mechanism which is preferably provided with hands and dials in the usual manner. The hour hand shaft in the center of the clock projects rearwardly and is provided with an extension 11 passing through a bracket 12 and carrying at its end a double dial disk 13 shown in Fig. 5 and which will hereinafter be described more in detail, the same being capable of adjustments to determine the time and duration of the operation of the light. Reducing gearing is interposed between the shaft 11 and the double dial disk whereby the disk rotates only once in twenty-four hours. This in the upper part of the bracket 12. The

lever 14L has a downwardly turned end 16 Fig. 1 carrying a cross piece or hell crank member 17 loosely engaging and co-acting with a second bell crank member 18 pivoted on a fixed support as shown in Fig. 5 for raising and lowering a shield 20 about the wick 21 of an oil lamp or the like 22. At one side of the bracket 12 is positioned a resilient spring arm 28 having a hook 24- adapted to catch over the rod 14 when the device is set, as shown more clearly in Fig. 3. The upper part of this member 23 is provided with a transversely extending portion 25 with an upper roughened or serrated surface adapted to co-act with a head of a match 26 clamped in the upper part of a support 27 which extends downwardly to the base and acts as a support for the end of the shaft 11. A wick or fuse 28 extends between the wick 21 and the head of the match being supported by a hook-30, or the like on the bracket 27.

From the above, it will be seen that as the disk 13 which is directly connected with the hour hand of the clock by means of the shaft 11 is rotated, the notch in the volute portion of the cam will eventually permit the lever 14 to drop to release the hook 24-, as shown more clearly in Fig. 3 and permit the striker 25 to spring backwardly under the action of its spring support 23 and ignite the match 26 which in turn lights the fuse leading to the wick 21. Simultaneously with this downward movement of the lever 14, the

protruding end 18 of the bell crank mecha-' shield 20 to drop down, a suflicient distance to expose the wick and permit the same to be ignited by the fuse 28.

Instead of setting the striker and using the, fuse and match, as herein shown, one end corner of the shield 20 may be cut away, as shown by the notch 31, thus always exposing a small corner of the wick which maybe left burning. The shield is automatically raised and lowered at the desired times by means of the clock mechanism'for as the disk 13 revolves and the volute cam increases in radius, the lever l l will be gradually raised until the shield 20 again covers the wick and extinguishes the flame, except for that small part'per'mitted to burn by reason of the notch 31. e

In Fig. 5 there is shown the details of construction of the disk 13. This disk preferably comprises two \volute cain members and a dial, one of the cam members being adjustable axially with relation to the other. If, for example, the device were applied to the operation ofa night lamp the dial would beset to turn the light-on at eight oclock in the evening and extinguish the same at four oclock in the morning, but as the nights grow longer, it will be necessary to turn on the lights earlier in which case one cam 32 would be advanced with respect to the other cam 33 and locked in adjusted position by means of the nut 34, whereby the light will be turned on at seven oclock and allowed to burn a correspondingly longer time in the morning. One of these disks is preferably provided with a dial 35 similar to the clock dial in order that the setting of the actuating notch with respect thereto may be more easily determined. It is thus seen that without material modification the mechanism herein shown may be applied to various uses.

The invention is simple and practical in construction as well. as reliable and eilicient in use and operation and is believed to accomplish in short all of the objects and advantages above set forth.

' Without further analysis, the foregoing will so fully reveal the gist of this invention that others can by applying current knowledge readily adapt it for various applications without omitting certain features that, from the standpoint of the prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention, and therefore such adaptations should and are intended to be comprehended within the meaning and range of equivalency of the following claims.

I claim:

1. In a device of the character described, in combination, a clock mechanism, a disk cam adapted to rotate in accordance therewith, a lever adapted to be actuated by the cam, a source of light having a wick, a shield about said wick, means for raising and lowering the shield connected with said lever, igniting means adapted to light the wick, and a striker adapted to engage said igniting means simultaneously with the lowering of the shield.

2. In combination, a clock mechanism, a source of light, means for controlling the intensity, of said light, cam mechanism rotatably mounted to move in accordance with said clock mechanism, and means controlled by said cam mechanism for regulating the position of said light controlling means, igniting means adapted to ignite the source of light, and a spring actuated striker adapted to ignite said igniting means simultaneously with the actuation of the light controlling mechanism.

In combination, a clock mechanism having a central shaft, a dial corresponding to the clock dial mounted on said shaft and rotatable therewith, a volute cam mechanism carried by said dial, a source of light comprising a wick, a shield adapted to be raised and lowered about said wick, means actuated by said cam mechanism for raising and lowering said shield at desired times according to the position of said volute cam mechanism, igniting means for igniting the wick and a spring actuated striker adapted to ignite said igniting means simultaneously with the lowering of the shield about said wick.

In testimony whereof I aliix my signature in presence of two witnesses.
